We have recently acquired the capability to perform fairly complex water flow simulations using a computer based flow analysis application. This system allows us to construct a model of an actual or theoretical water distribution in a highly detailed and organised manner. This model includes pipes, valves, pumps, tanks and can be run over an extended period of time based on various demands, pressures and other related variables.

The simulation uses Hazen-Williams, Darcy-Weisbach or Chezy-Manning headloss methods and includes minor headlosses for bends, tees, valves and other fittings.

We can also model the impacts of leaks on distribution systems.

This capability is particularly useful in the case of larger buildings, townhouse complexes or campuses that are experiencing problems with their water distribution system. It can also be used on smaller buildings, but in the case of a small house you don't have to model the problem - it's apparent just by doing some basic measurements and looking at it! We are able to model an unlimited number of pipes and nodes so in theory could model an entire town, but that's not part of our core business. We wish to use this as a tool to identify and quantify water supply problems in specific areas and then do the nesessary pipework to remedy the situation.

We are able to conduct a detailed analysis of the system without having to dig it up! The process begins with baseline data collection - starting at the water supply all the way through to the individual taps. Pipe lengths and diameters are measured and all visible detail is included - like valves, storage tanks, etc. Supply pressure is measured and the flow potential quantified. Flow expectations at the end points are quantified.

Once this is done the data is fed into the simulator and run - either as a once off simulation or over a given time period so as to more accurately model a system with varied supply and demand. We are then able to see what the characteristics of the system should be and compare this to it's actual performance. If the system is performing as it has been designed, then we can simulate changes to the system that will improve it. This may include the replacement of pipes with bigger ones or the addition of a storage tank and/or pump to reduce the impact of high demand and low supply situations.
